Public bug reported:
Any attributes set for local variables aren't exported to subshells
correctly, resulting in incorrect behaviour.
A reproducer:
```bash
#!/bin/ksh
function called_function_ext {
echo "In function_ext: int_typeset_declared_in_func_exported:
${int_typeset_declared_in_func_exported}"
}
function call_from_main {
typeset -i int_typeset_declared_in_func_exported=444
export int_typeset_declared_in_func_exported
echo "In call_from_main: int_typeset_declared_in_func_exported:
${int_typeset_declared_in_func_exported}"
called_function_ext
}
call_from_main
```
It outputs:
```
In call_from_main: int_typeset_declared_in_func_exported: 444
In function_ext: int_typeset_declared_in_func_exported: 3421236
``
Whereas correct output should be:
```
In call_from_main: int_typeset_declared_in_func_exported: 444
In function_ext: int_typeset_declared_in_func_exported: 444
```
Upstream bug: https://github.com/ksh93/ksh/issues/465
This has been fixed in Noble. Intending to backport to Jammy.
